IMPROVEMENT IN ROTARY CHURNS.

Specification forming part of Letters Patent No. 186,174, dated January9, 1877; application filed September 9, 1876.

To all whom it may concern:

Be it known that we, EDWARD F-SNEAD and HENRY C. STINNETT, of Buchanan,in the county of Botetourt and State of Virginia, have invented a newand valuable Improve- .ment in Ghurns; and we do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference beinghad to the annexed drawings,making a part of this specification, and to the letters and figures ofref- .erence marked thereon.

Figure 1 of the drawings is a representation of a central verticalsection of our churn, and Fig. 2 is a side elevation thereof. Fig. 3 isa horizontal vertical sectional view, and Fig. 4 is a plan view of ourchurn without gearing dasher-supporting frame.

This invention relates to improvements in churns bar ing rotary dashers;and it consists in the combination of the devices hereinafter describedand claimed.

In the annexed drawings, A designates an upright cylindrical churn -box,which is provided with vertical grooves or channels A A, adapted toreceive the stilesor standards B B of a daslier-supporting frame. Saidstand- I ardsrare connected at the bottom by crosspiece B and near thetop of said churn-box by upper cross-piece B. Said standards also extendvertically above the top of said churnbox, and, with said cross-pieces,complete the said supporting-frame. G designates a vertical rotatingdasher-shaft,journaled in the middle parts of cross-pieces B and B, andprovided with radial dasher'arms c c. The upper journal of said rotatingdasher-shaft is pro longed, so as to form a vertical and rotating rod,(3, which carries a bevel-geared pinion or v small wheel, D. Said pinionmeshes with a 7 vertical bevel-geared wheel, E, which is journaled, byhorizontal rotating shaft F, in boxes G G, that are secured to standardsB B near the upper ends thereof. Said horizontal rotating shaft isconnected to and rotated by crank-arm H. To the inside of standards B B,within the said churn-box A, are secured two opposite series ofinwardly-extending rods or bars, b b. Said bars alternate with the saiddasher arms or bars 0 0, so that when the said crank is operated thesaid revolving dasherarms b I) turn through the spaces between the saidfixed bars a c. This stirs and churns the milk or cream veryeffectually. I I designate the two segmental sections of a cover to saidchurn-box. Said sections are recessed rectangularly at 'i t', to receivestandards B B, and perforated centrally at i, to allow the passage ofvertical rod 0, already described. They are also provided with handles II upon their tops to facilitate their removal. For the same purposestandards B B may be detachabl y secured in grooves or channels A A.

Rod 0, bevel-geared pinion D, bevel-geared wheel E, and shaft F are allconstructed of metal, and preferably of iron. The remaining devices arepreferably constructed of wood.

What we claim as new, and desire to secure by Letters Patent, is-

l. A churn-box having opposite interior longitudinal grooves adapted toreceive a dasher-supporting frame, which extends entirely across theinterior of the churn-body, substantially as and for the purpose setforth.

2. The churn-box A, having opposite interior vertical grooves A A, incombination with the removable frame B B B, provided with arms b b, andshaft F, having bevel-gear E, and the dasher-shaft 0, provided with arms0 and bevel-gear D, substantially as and for the purpose set forth.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
